Committee on Natural Resources - mars-6:hrs06RES1324_100610.1 - Longworth 1324 - The Short and Long Term Impacts of the Deepwater Horizon Oil Spill (Part 1 of 2) - Subcommittee on Insular Affairs, Oceans and Wildlife Oversight. Today is the first of three hearings that the Subcommittee will hold on the Deepwater Horizon oil rig explosion. This is in addition to two Full Committee oversight hearings already held by Chairman Rahall and two oversight hearings Subcommittee Chairman Costa will hold later this month. As the Committee with primary jurisdiction over offshore oil and gas drilling, we will exercise our oversight responsibilities to the fullest extent, and we take these responsibilities very, very seriously.
